I PUMP Filed May 31, 1928 3 Sheets-Sheet 3 j Xi I [Ju Attorney Inverztars- Patented June 3, 1930 UNrrEo STATES WILLIAM T. WHEAT AND AUGUST STQIfl'E, 01E IYIALIN, OREGON PUMP Application filed May 3 1, 1928. Serial No. 281,682.

The present invention relates to a pump and has for its prime object to provide a pump of the rotary type which may operate at a relatively low rate of speed and dis place a relatively high quantity of water.

Another very important object of the invention resides in the provision of a rotary pump including blades movable in a compartment and a valve structure in the compartment associated with the blades so as to cause the blades to draw water into the compartment and force water therefrom in each revolution.

A still further very important object of the invention resides in the provision of a pump of this nature which is exceedingly simple lnits construction, compact and con- 7 venient in its arrangement of parts, strong and durable, comparatively inexpensive to construct, not likely to easily become out of order, thoroughly efficient and reliable in its operation.

With the above and numerous other objects in view, as will appear as the description proceeds, the invention resides in certain novel features of construction and 1n the combination and arrangement ,of parts as will be hereinafter more fully described. and claimed. i

In the drawings: Figure l is a top plan view of the pump embodying the features of our invention. Figure 2 is an end elevation thereof. Figure 3 is a similar view with the head plate removed. 7 Figure 4 is a horizontal section taken substantially on the line 4l-4= of Figure 3.

Figure 5 is a vertical longitudinal section taken substantially on the line 5-5 of Figure 2, and

Figure 6 is a perspective view of the valve. Referring to the drawings in detail, wherein like numerals of reference denote like parts throughout the several views, it will 3 be seen that a casing 5 is formed with a displacement compartment 6 and a valve compartment 7. The displacement compartment 6 is concentric with respect to the axis of the casing, while the valve compartment 7, rises upwardly 'ffrein' said axis- .is head plate 8issecured to the casing 5, to close the com partnient 6, by means of screws 9 or in any other suitable manner. A hearing 10 is dis- 7 posed in the casing 5, remote from the head plate 8 and the head plate 8 is provided with an aligned bearing 11, having associated therewith a packing nut 12. A shaft lt is journaled'at one end in the bearing 10, and through. the bearing 11, and at its, other end has a pulley 15, for rotating this shaft 14: from any suitable source of power.

A hub 16 is keyed to the shaft 14, as at 17 and has a pair of oppositely radiating blades 18 extending therefrom tooperatein the chamber 6. At the top of the chamber 6 of thecasing 5, there is provided a pair of inlets and outlets inthe form of openings 20. These openings 20 are located one to each sideof the valve compartment 7'. A cap plate 21 is disposed over the compartmer t- 7, being held in place by screws 22 or in any other suitable manner. This cap plate has a bearing 23, in which is journaled a shaft 24. The lower end of the 24 has thereon a bevelled pinion 25, meshing with a bevelled pinion 26 on the shaft-14. These bevelled pinions 25 and 26 are of the same size, so that the shaft 24, makes one completerevolution to each complete revol lution of the shaft 14. Acylindrical valve 28 is keyed on the shaft 24, as at 29, 'and is provided, on opposite sides with longitudie nally extending peripheral channels 30, which taper upwardly in width, for accommodating the blades 18.

The casingfi, in the present instance is provided with supporting legs but, of course may be mounted in any suitable I manner. 7

Referring to Figure 3, it will be seen that if the rotor consisting ofthe hub 14 and the blades 18 is rotated in a clockwise direction, the right hand opening 20 will function as an inlet and the left hand opening 20 will function as an outlet. Following this example out, it will be seen that as the rotor rotates and the vein 18 leaves the outlet, it createsa suction to dranv in fluid and as the other blade passes th rotating valve in one of the 20 thereof, it ushes the water sucked in by the preceding blade and the Water is pushed out through the outlet opening 20. The water moves around only once, because of the valve structure 28, as will be apparent. Obviously, the rotor may be rotated in the opposite direction and the left hand opening becomes the inlet and the right hand opening the outlet.

It is thought that the construction, operation, utility and advantages of this invention will now be quite apparent to those skilled in this art, without a more detailed description thereof. The present embodiment of the invention has been disclosed in considerable detail, merely for the purpose of exemplification, since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description. It will be apparent, however, that changes in the details of construction, and in the combination and arrangement of parts may be resorted to, Without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described our invention, whatwe claim as new is:

A rotary pump of the class described comprising a casing having an annular dislacement compartment therewith with inlet and outlet openings at the top, and a valve compartment rising from the axis of the casing and between said openings, a rotor in the displacement compartment including a hub and a pair of oppositely disposed blades, a shaft journaled in the compartment and on which the hub is fixed, a second shaft journaled in the valve compartment and having a cylindrical valve thereon provided with peripheral longitudinal channels to receive the blades, means gearing the shafts to rotate at the same rate simultaneously, said casing having a head plate to close the displacement compartment, and a bearing in the head plate to receive the first mentioned shaft, and a bearing in the casing to also receive the first mentioned shaft, a cap plate for closing the upper end of the valve compartment, and a bearing in the cap plate for receiving the second mentioned shaft, said cap plate being constructed to accommodate said inlet and outlet.

In testimony whereof We affix our signatures.
